Runes for Modern English
This is the latest version of my adaptation of runes to Modern English. Note that it is not a direct adaptation of the Anglo-Saxon fuþorċ, but rather an adaptation of J.R.R. Tolkien's adaptation (and, I suppose, the elaboration on Tolkien's Hobbit runes that made their way into the Ultima games).
I begin with Tolkien's rune-writing mode, which is a near glyph-for-glyph (or sometimes -digraph) substitution cipher for Latin letters, because Anglo-Saxon runes very nearly corresponded one-for-one with Latin letters in Old English; and one can easily imagine that if runes had continued to be used in English through the Middle and Early Modern English periods, the same drift that affected Latin script in English may very well have carried runes along with it (as, indeed, happened for the Scandinavian runes).
How does my version differ from Tolkien's? Many of the Modern English rune names are his, but I've altered a few here and there ("elk" instead of "elm" for the E rune, "ghost" instead of "guest" for the GH rune). "Ouph" and "quern" are pretty obscure, but the former was chosen because it's an archaic English synonym for "elf," which seems a fitting tribute to Tolkien (and because English nouns that start with "ou-" are pretty hard to come by); and I use the latter because that word may actually be related to the Old English name of the Q rune, cweorð.
The biggest revision is the handling of C, K, Q, and Z, which are something of a mess in Tolkien's system (he used the C rune for both C and Q, a slightly different version of the same rune for K, and the K rune for Z). I use the Old English C rune only for C; the K rune for K; the doubled K rune for CK; the Q rune for QU; and the similar but somewhat mysterious IE/EO/H rune for Q alone. I use a variant form of the S rune which happens to look like an inverted C rune (or the Norse K rune) for Z.
Secondarily, I've taken the two forms of the OE rune that Tolkien used for EE and OO and repurposed them for the much more frequently-occurring OU and OW digraphs. (It doesn't hurt that the single-stem form of this rune that I use for OW just so happens to look rather like a doubled W rune that occurs in some very early runic inscriptions.) This change saves some pen-strokes, let me tell you; and there's little need for any rune to represent two of the same Latin letter in any case, because even Tolkien sometimes used a dot under a rune as a sicilicus / gemination mark.
Sample text is the Lament for the Rohirrim from The Two Towers: "Where now are the horse and the rider? [etc.]"
